I work at one of the big "nefarious corporate" companies, and my life is incredibly happy; I'm proud of getting a job here and proud of the work I do. More importantly, I have time and money to travel, play music, live a healthier lifestyle and generally enjoy life outside of (and in addition to) work. Who gives a shit if "The Man" is getting rich off my work? I don't envy what he has. Being able to afford a Lotus wouldn't make me nearly as happy as spending time with my wife.
If you feel compelled to pursue a startup because it's your passion, that's wonderful...but doing so with the expectation of riches is unrealistic, statistically speaking. Plus, growth in wealth is proven not to linearly increase happiness.
EDIT: But who am I to tell you how you (or anyone) how to live their life? If that's your path, then by all means pursue it.
